Keep seeing this post, over and over. The solution is very simple:

Sick of entering your serial every time you play? Right underneath the "Forgotten Password" button on the login screen, there's an option to save your serial number so you don't have to enter it every time. This also (for me) fixes the "serial number already in use" issue.

If this works for you, vote to sticky the thread.

EDIT: Also, if this works for you, please don't use this forum as your personal blog/vent spot. Really tired of seeing "BAAAAAWWW CRYTEK svckS THIS GAME IS BROKEN!!!!!!111`" posts. Thanks.

No, this does not work for me.

It looks like EA double batched Crysis 2, which is actually a FOMC and Sarbanes-Oxley violation. Failure in system of internal controls in inventory distribution.

Thank you very much! I was able to join a game with no problem after entering the serial on the main login screen (with dashes), just like you suggested!

Thanks again!

It allows you to enter a multiplayer game but next time you start the game you have to enter the CD key again.

IT DOES NOT WORK FOR EVERYONE

I got this and the key not being able to be saved fixed by going to C:\Users\"your user name"\Saved Games right click on crysis2 folder and make sure the read only is not on
